Even if the creator specifically had eugenics in mind, I think he stumbled upon a greater truth.

Consider this. You can take anyone from any group in your nation, place them in a different nation, with a different culture, and they will adopt the mannerisms and accents of that culture.

We focus on race constantly, but it's clear that culture drives the norms that we see in any group. And culture may be persistent (especially now with technology allowing every culture to potentially spread everywhere), but it's not intrinsic.

With this framing, I interpreted Idiocracy's intro as being about a culture of intelligence or learning being harder to maintain in a modern world, than a culture of apathy or fun.

I watched this movie really late. Let's say within the past 2 years or so. After watching it, all I could think was, "This isn't a comedy, it's a tragedy."

It felt way too close to home.
